BROOMFIELD, Colo., April 17, 2017 /PRNewswire/ -- "Interventional orthopedics in pain medicine practice" was recently published by Elsevier as a chapter in Techniques in Regional Anesthesia and Pain Management. The chapter, authored by Regenexx founder Christopher J. Centeno, MD examines less invasive ways to treat orthopedic pain and injuries through autologous biologics, such as stem cells and platelet rich plasma (PRP), and the shift from surgical orthopedics to interventional orthopedics.

Interventional orthopedics utilizing advanced technologies, such as ultrasound and X-ray guidance, precise percutaneous injections of autologous biologics, and bone marrow concentrate, (BMC) expand nonsurgical options in the field of orthopedics. Citing the dramatic reduction in cardiac surgery rates since the adoption of the specialty interventional cardiology, the authors reveal, "We are poised on the brink of the same change in orthopedic care." The authors also state, "The field of autologous biologics has the potential to alter the playing field of orthopedic care by allowing percutaneous injections to replace the need for more invasive orthopedic surgeries."

The chapter covers three important tenets in the developing field that will allow Interventional Orthopedics to alter traditional orthopedic care in the future. First is the rapid expansion of injectates (material being injected), such as stem cells and PRP, that can help heal damaged tissue and that can effectively treat musculoskeletal tissues. Second is the precise image-guided placement of those injectates into those damaged tissues. And third is the development of new tools that will advance this regenerative-medicine technology. The chapter also highlights research that supports the use of bone marrow stem cells and the importance of education standards and organization, training, and retraining of physicians to meet these standards.

Last year, the Centers for Medicare and Medicaid Services enacted a significant policy change improving access to blood and marrow transplants for Medicare patients diagnosed with life-threatening blood cancers. The change came in the form of a Medicare rule on how outpatient blood and marrow transplants are reimbursed by the federal health care program beginning on Jan. 1, 2017.

While this move a step in the right direction, this rule does not address the vast majority of transplants (97 percent) that are performed in the inpatient setting. Sadly, Medicare continues to provide inadequate reimbursement to hospitals performing inpatient transplants and this limitation threatens to limit access to seniors needing this lifesaving therapy.

It is estimated that a new patient is diagnosed with a blood cancer every three minutes. More than 170,000 Americans will receive a blood cancer diagnosis like leukemia, lymphoma or myeloma this year alone; approximately 1.2 million Americans currently live with these diseases.

Blood and marrow transplants using a donor (allogeneic transplants) remain the only curative treatment for many blood cancers. The process of transplantation typically involves treating the patient with chemotherapy and then restoring healthy cells in the recipient by an infusion of blood or bone marrow stem cells, obtained from a matched related or unrelated donor or from umbilical cord blood. These donor cells also help to eliminate any cancer cells that survive chemotherapy.

The fatal blood diseases that require transplants occur most commonly in older individuals, who are also most likely to be covered by Medicare. Historically, the risks of transplant were too great to allow us to safely transplant many seniors. However, rapid clinical advances have resulted in dramatically improved outcomes in older adults. In fact, patients over the age of 65 are now the most rapidly growing population in U.S. transplant centers.

Despite the overwhelming clinical evidence demonstrating the curative potential of transplants in older patients, transplant access for seniors is threatened by Medicares chronic underfunding for both the transplant itself and the costs required to obtain matched bone marrow or cord blood. Medicare, for the most part, adequately reimburses transplants of solid organs such as hearts and lungs, appropriately covering the costs of acquiring those organs.

Surprisingly, Medicare treats the cost of acquiring bone marrow differently. Currently, Medicare pays for the cost of acquiring bone marrow and the transplant procedure and hospitalization in a single payment. Unfortunately, the amount currently reimbursed falls well short of the costs of providing the complex care required for blood and marrow transplant recipients, who are vulnerable to complications including infections in the post-transplant period. Unlike solid organ transplants, the cost of obtaining unrelated donor blood, bone marrow or cord blood is not directly and completely reimbursed.

This inadequate reimbursement threatens the ability of transplant centers to continue to take on the complex care of seniors with blood cancers. Unless reimbursement policies change, some seniors may face limited access to their only curative treatment option.

Thanks to national investment in research and continued innovation, seniors diagnosed with cancer today have more treatment options than they had in the past. Poor federal reimbursement policies must be updated to provide patients with access to the treatments that offer them the best possible outcomes, including transplantation.

While last years policy change was a marked improvement in reimbursement for those three percent of transplants occurring in the outpatient setting, it is important that similar payment reforms now address themajority of blood and marrowtransplants that are performed as inpatient procedures.

I urge Medicare to revise its payment policies for blood and marrow transplants to strengthen reimbursement in the inpatient hospital setting to ensure American seniors the full range of life-saving treatment options for cancer that they deserve.

Sumitomo Dainippon Pharma Co Ltd has ordered cell culture technologies from Hitachi as part of its effort to develop a treatment for Parkinsons disease.

The order financial terms of which were not provided will see Hitachi supply automated cell culturing technologies designed for the manufacture of induced pluripotent stem cells (iPS).

Dainippon is developing a cell therapy for Parkinsons-related dopamine neuron loss and neurodegeneration in collaboration with both Hitachi and Center for iPS Cell Research and Application, Kyoto University (CiRA).

Part of the project which is funded by the Japanese Agency of Medical Research and Development (AMED) - involves the development of processing methods and technologies for the production of stem cells for regenerative therapies.

The Japanese drug firm has announced several regenerative medicine-based research projects in recent years, beginning in 2015 when it partnered with Sanbio to develop SB623, an allogenic cell therapy for ischemic stroke to improve motor abilities.

Regenerative meds

Regenerative medicine which engineers or replaces damaged cells within human patients has become a popular area of research in Japan sinceShinya Yamanaka won the 2012 Noel Prize for medicine for the discovery that mature cells can be reprogrammed to become pluripotent.

Regenerative medicine is also a big focus for the Japanese Government.

Laws introduced in November 2014 therevised pharmaceutical affairs law and newregenerative medicines legislation mean such products could be reviewed and approved in just two years, if deemed to be effective.

Japans Government further underlined its commitment to regenerative medicine in its budget in January 2015, allocating Y2.5bn ($20.8bn) to the industrialisation of regenerative medicine evaluation fundamental technology development business.

It would seem the beautiful foxglove plant has more uses than just the garden.

A novel drug screen in liver-like cells shows that cardiac glycosides, which are found in the leaves of the digitalis or foxglove plant, could reduce low-density lipoprotein (LDL) cholesterol differently than statins, potentially providing a new treatment for patients.

The foxglove plant in bloom on MUSC's campus.

These findings were reported by the Medical University of South Carolina researcher Stephen A. Duncan, D.Phil., SmartState Chair of Regenerative Medicine at MUSC, and colleagues in the April 6 issue of Cell Stem Cell.

Duncan said the glycosides were identified through a stem cell screen for compounds that could be used off-label for the treatment of high cholesterol. The nice thing about finding new uses for drugs already on the market is that they can be used relatively quickly in patients because most of the needed safety trials have already been completed.

Not everyone with high LDL cholesterol responds to statins. Statins increase levels of a cell surface receptor that removes LDL cholesterol from the bloodstream. However, statins do not work in patients with familial hypercholesterolemia (FH), who have a rare mutation in that receptor. It is an inherited disorder that leads to aggressive and premature cardiovascular disease. FH patients have very high cholesterol and can die of cardiovascular disease by their forties. The existing drugs for FH can cause fatty liver disease, and the best treatment is a liver transplant.

Duncan and his graduate student Max Cayo, who is finishing his M.D. at the Medical College of Wisconsin, developed a drug screen to identify an alternative to statins. Apolipoprotein B (apoB) is a molecule that liver cells use to make LDL. Drugs that decreased apoB could potentially lower cholesterol independently of the LDL receptor in FH patients and also in patients with other forms of high cholesterol.

FH was a perfect model for testing alternatives to statins. Yet the rarity of FH meant these liver cells were scarce. Duncans group made induced pluripotent stem cells out of skin fibroblasts taken from a single patient with FH. Stem cells continually double their numbers while in culture. This meant that a sample of converted skin cells from a single patient with FH provided a renewable source of liver-like cells that retained the mutation.

The group tested these liver-like cells with the SPECTRUM library, a collection of 2,300 pharmaceuticals, many of which have reached clinical trials. Surprisingly, all nine cardiac glycosides in the collection, some widely prescribed for heart failure, reduced apoB in liver-like cells from the patient with FH. In further tests, they also lowered apoB in human hepatocytes and in mice engineered to grow normal human livers without the FH mutation.

Next, the team combed through more than five thousand medical records of patients prescribed cardiac glycosides for heart failure who also had LDL cholesterol records. Similar drops in LDL levels were observed in these patients as in a matching group of patients prescribed statins.

This study provides the first evidence that cardiac glycosides could potentially reduce LDL cholesterol independently of the LDL receptor, where statins act, by reducing apoB.

The cardiac glycosides are always prescribed with care, as they are known to be toxic at high doses. However, they could offer inexpensive life-saving options for patients with FH. Additionally, a cardiac glycoside in a low dose could conceivably provide an added benefit to patients already taking a statin. Duncan is exploring plans for a clinical trial that would determine the correct dose in hypercholesterolemia patients.

Using patient stem cells to screen drugs that are already on the market is a great way to investigate treatments for liver diseases.

There are so few livers available for transplant, Duncan said. Having the stem cell model where we make liver cells in the culture dish opens up a possibility of using this not only to investigate a disease, but also as a way to discover drugs that could fix a disease.

It will be several weeks before Jonathan Pitre finds out if his second stem-cell transplant was successful. Tina Boileau / -

The perilous wait now begins for Jonathan Pitre.

Pitre, 16, was transfused with blood and marrow drawn from his mothers hip late Thursday afternoon. The stem-cell rich material holds the power to alter the course of Pitres aggressive skin disease, epidermolysis bullosa (EB), and change his life.

So far, so good, saidPitres mother, Tina Boileau.

It will be several weeks before Pitre finds out whether the transplant has worked its magic.

While waiting for that answer, theRussell teenager will have to travel the most difficult part of his medical journey: a time when his immune system is at its lowest ebb, and when he feels the full effects of high-dose chemotherapy and radiation.

His physician, Dr. Jakub Tolar, has warned that the period represents the highest risk for complications, the most common of which are infections and graft-versus-host disease (GVHD). It is a potentially life-threatening situation in which the implanted stem cells produce T-cells that attack normal cells.

In about two weeks time, doctors will start to look for signs that Boileaus stem cells have successfully established themselves in Pitres bone marrow.The presence of white blood cells is one of the earliest signs of stem-cell growth; an improvement in the condition of Pitres skin could also signal that the stem cells have started to work.

Last year, after his first stem-cell transplant, Pitre and his mother were thrilled when doctors discovered new white cells in his bloodstream. But their hopes were crushed when tests showed Pitres own stem cells had recolonized his bone marrow, and were producing the cells.

This time, Boileau said, they will wait to see more lab results before getting their hopes too high.

I think we will have that uncertainly until we know for sure through skin and bone marrow biopsies that the engraftment worked, she said.

Boileau went into surgery early Thursday morning to have blood and bone marrow drawn from her hip. She was at her sons bedside later in the afternoon to watch as the stem cells dripped through an intravenous tube connected to the right atrium of her sons heart.

If the transplant works, Boileaus stem cells will establish themselves in her sons bone marrow, grow, divide and make new blood cells equipped with the power to provide Pitre with the key protein he needs to rebuild his damaged skin.

Because of a bone marrow donation from a 20-year-old in Germany, Central Michigan University student Kyle Tanner has a new chance at life.

This is why we encourage students at CMU to become registered as acandidate to donate bone marrow or stem cells.

You can help save lives.

When Kyle Tanner learned he had Fanconi anemia at age 16, he didnt understand the toll the bone marrow disease would take on him.

It made definitely me anxious and it made me more inclined to do things that I wouldnt have otherwise did if I didnt know I had a life-threatening disease, Tanner said.

At any given moment, thousands of Americans are seeking an unrelateddonor for a potentially life-saving marrow transplant.

Donations help people diagnosed with blood cancers like Leukemia and other diseases.

For Tanner, a 22-year-old Hudson native, two transplants saved his life six years after he was diagnosed with a life-threatening bone marrow disease.

Donating bone marrow is not often talked about, but is vitally important especially on college campuses.

Because of our age, students are the bestdonors.

Young people have more and higher quality cells, which leads to a higher chance the patient receiving the transplant will survive.

While registries allow people ages 45-60 to donate, thosewho are18-44 are prime donors.It is also free to register for people in this age range.

The registration process has been made simple by organizations like Be The Match, which is operated by the National Marrow Donor Program. It is how Tanner got paired with his donor.

If you're registering online, Be The Match mails you a mouth-swab kit. You mail it back to them and it goes to the lab. Results come back in 8-10 weeks. If you qualify, you are placed on the registry and are able to be called on to donate.

According to Be The Match, only 25 percent of people donate actual bone marrow, which is extracted from the pelvic bone. The other 75 percent of donations are peripheral blood stem cell donations. Donating marrow can sometimesinvolve an over-night stay at the hospital, while a stem cell donation is similar to donating blood or plasma.

Be The Match also has traveling drives, which can be hosted by individuals and organizations.

We think it's a great idea for our Student Government Association or other registered student organizations to consider hosting a drive at CMU.

Raising awareness of the necessity to donate marrow and stem cellsand the know-how is important. Many of us know someone diagnosed with Leukemia or other diseases that desperately need a stranger to be their savior.

For people like Tanner, it took someone to decide to make a difference in his case, it wasa 20-year-old from Germany.

CMU students can make the decision to save someones life, too. Consider getting registered and potentially saving someone's life.

Like private investigators on a stake out, St. Jude Childrens Research Hospital scientists used patience and video surveillance-like tools to identify cells that trigger blood cell development. The findings offer clues for making blood-forming stem cells in the laboratory that may ultimately help improve access to bone marrow transplantation.

The research will likely open new avenues of investigation in stem cell biology and blood development and provide insight to aid efforts to make transplantable hematopoietic stem cells in the lab, said corresponding author Wilson Clements, Ph.D., an assistant member of the St. Jude Department of Hematology.

Blood-forming stem cells are capable of making any type of blood cell in the body. They are also used in transplant therapies for cancers like leukemia or other blood diseases like sickle cell. They are starting to be used to deliver gene therapy. However, a shortage of suitable donors limits access to treatment, and efforts to produce blood from pluripotent stem cells in the laboratory have been unsuccessful. Pluripotent stem cells are the master cells capable of making any cell in the body.

All blood-forming stem cells normally arise before birth from certain endothelial cells found in the interior blood vessel lining of the developing aorta. This processincluding how endothelial cells are set on the path to becoming blood stem cellsis not completely understood.

Clements and first author Erich Damm, Ph.D., a St. Jude postdoctoral fellow, have identified trunk neural crest cells as key orchestrators of the conversion of endothelial cells to blood stem cells. Trunk neural crest cells are made in the developing spinal cord and migrate throughout the embryo. They eventually give rise to a variety of adult cells, including neurons and glial cells in the sympathetic and parasympathetic nervous system, which control feeding, fighting, fleeing and procreating.

Using time-lapse video, the researchers tracked the migration of neural crest cells in the transparent embryos of zebrafish. Zebrafish and humans share nearly identical blood systems, as well as the programming that makes them during development. After about 20 hours, the neural crest cells had reached the developing aorta. After hour 24, the migrating cells had cozied up to the endothelial cells in the aorta, which then turned on genes, such as runx1, indicating their conversion to blood stem cells.

The investigators used a variety of methods to show that disrupting the normal migration of neural crest cells or otherwise blocking their contact with the aorta endothelial cells prevented the birth of blood stem cells. Meanwhile, other aspects of zebrafish development were unaffected.

Researchers have speculated that the endothelial cells that give rise to blood-forming stem cells are surrounded by a support niche of other cells whose identity and origins were unknown, Damm said. Our results support the existence of a niche, and identify trunk neural crest cells as an occupant.

Adult bone marrow includes niches that support normal function and notably feature cells derived from trunk neural crest cells.

The findings also suggest that trunk neural crest cells use a signal or signals to launch blood stem cell production during development. The researchers have eliminated adrenaline and noradrenaline as the signaling molecules, but work continues to identify the signaling proteins or small molecules involved.

The research was supported in part by a grant (R00HL097) from the National Heart, Lung and Blood Institute of the National Institutes of Health; the March of Dimes; and ALSAC, the fundraising arm of St. Jude.

Cells Essential for 'Birth' of Blood Stem Cells Revealed - Technology Networks

As a kid, I was always intrigued with potions and products. My father worked as a scientist, whose specialty was chemistry as well as business. For many years he worked as the Director of Research and Development for the Mennen Company. Perhaps this is where my love of products and researching products began.

Like many women, my skin can be difficult at times. I have eczema which makes it intermittently sensitive, so I have to be careful of the products I use. While researching these products, I also looked into the science supporting them.

As fate would have it while exploring some interesting articles on my Twitter feed recently, I came across an intriguing tweet I just couldnt ignore. It was a tweet by a glamorous NYC dermatologist who was talking about how excited she was to receive her Lifeline Skin Care products in the mail. Her excitement was so infectious; I decided to look into these products for myself, and looking into them, ultimately led me to buy them and to contact the company to see if we could collaborate together, so I could spread the word.

While researching Lifeline Skin Cares products, I also looked into the science supporting them. Lifeline Skin Care products use something I had never heard of before; they use human, non-embryonic stem cells as one of the main ingredients to help tone and reduce the signs of aging.

Science

As a therapist, I not only look for products that work well and that I believe in, but also look at the philosophy of the company. Lifeline Skin Care was a socially conscious company and fit that standard.

Clinical Trials

The original goal for these researchers was to find a cure for diabetes and Parkinsons disease. These scientists created the first non-embryonic human stem cells. This discovery made finding cures for Parkinsons disease and corneal disease more promising. Currently, some of ISCOs most promising research is in the field of Parkinsons disease.

Parkinsons disease (PD) is a long-term degenerative disease of the central nervous system. It mainly affects the motor system and its symptoms usually have a slow-onset. In early stages, the disease is characterized by shaking, slow movement, difficulty in walking, and rigidity. In time, thinking and behavioral problems may occur. Advanced stages of the disease bring dementia.

International Stem Cell Corporation (ISCO), is the parent company of Lifeline Skin Care and has devoted many years of research to improve this terrible disease. The company has developed a unique method of creating human neural stem cells which when introduced into the brain, promote the recovery of dopaminergic neurons, the brain cells that are originally affected and cause the disease symptoms. ISCOs preclinical studies showed that the administration of these neural stem cells were safe and improved motor symptoms. To date, 3 of the planned total of 12 patients, have entered the clinical trial and have received neural stem cells. At this point in time, all patients have been discharged from their hospital settings and are observed to be meeting clinical expectations.

Lifeline Skin care (LSC) - a subsidiary of ISCO - uses the extracts from human stem cells, (produced by ISCO), and developed for the skin in order to improve the signs of ageing. The latest technology being used to advance a cure for PD is now available for the skin in a line of products produced by LSC. The profits from the sale of these skin care products go directly to ISCO in order to fund the development of a therapy for PD.

From a skincare perspective, not only did Lifeline Skin Cares products feel good on my face, but I started to notice that my skin appeared brighter and less wrinkles, especially around my eyes (love that!).

From a psychological perspective, the younger we look and feel, the more optimistic and hopeful we tend to be about life and future options. I like the idea of feeling young, looking forever fabulous and most of all, being healthy.

Fortunately, Lifeline Skin Care found a way to help women and men look and feel their very best while scientists from their parent company work toward eradicating illness by using their special non-embryonic stem cell technology. Beauty is more than skin-deep; beauty can be on a mission, too.

Researchers from the University of Illinois at Chicago have identified a molecular switch that converts skin cells into cells that make up blood vessels, which could ultimately be used to repair damaged vessels in patients with heart disease or to engineer new vasculature in the lab. The technique, which boosts levels of an enzyme that keeps cells young, may also circumvent the usual aging that cells undergo during the culturing process. Their findings are reported in the journal Circulation.

Scientists have many ways to convert one type of cell into another. One technique involves turning a mature cell into a pluripotent stem cell one that has the ability to become any type of cell and then using chemical cocktails to coax it into maturing into the desired cell type. Other methods reprogram a cell so that it directly assumes a new identity, bypassing the stem-cell state.

In the last few years, scientists have begun to explore another method, a middle way, that can turn back the clock on skin cells so that they lose some of their mature cell identity and become more stem-like.

They dont revert all the way back to a pluripotent stem cell, but instead turn into intermediate progenitor cells, says Dr. Jalees Rehman, associate professor of medicine and pharmacology at UIC, who led the team of researchers. Progenitor cells can be grown in large quantities sufficient for regenerative therapies. And unlike pluripotent stem cells, progenitor cells can only differentiate into a few different cell types. Rehman calls this method to produce new cells partial de-differentiation.

Other groups have used this technique to produce progenitor cells that become blood vessel cells. But until now, researchers had not fully understood how the method worked, Rehman said.

Without understanding the molecular processes, it is difficult for us to control or enhance the process in order to efficiently build new blood vessels, he said.

His group discovered that the progenitors could be converted into blood vessel cells or into red blood cells, depending on the level of a gene transcription factor called SOX17.

The researchers measured the levels of several genes important for blood vessel formation. They saw that as progenitor cells were differentiating into blood vessel cells, levels of the transcription factor SOX17 became elevated.

When they increased levels of SOX17 even more in the progenitor cells, they saw that differentiation into blood vessel cells was enhanced about five-fold. When they suppressed SOX17, the progenitor cells produced fewer endothelial cells and instead generated red blood cells.

It makes a lot of sense that SOX17 is involved because it is abundant in developing embryos when blood vessels are forming, Rehman said.

When the researchers embedded the human progenitor cells into a gel and implanted the gels in mice, the cells organized into functional human blood vessels. Skin cells that had not undergone a conversion did not form blood vessels when similarly implanted.

When they implanted the progenitor cells into mice that had sustained heart damage from a heart attack, the implanted cells formed functional human blood vessels in the mouse hearts and even connected with existing mouse blood vessels to significantly improve heart function.

The human adult skin cells used by Rehmans team can easily be obtained by a simple skin biopsy.

This means that one could generate patient-specific blood vessels or red blood cells for any individual person, Rehman said. Using such personalized cells reduces the risk of rejection, he said, because the implanted blood vessels would have the same genetic makeup as the recipient.

Rehman and his colleagues noticed something else about the progenitor cells they had elevated levels of telomerase the anti-aging enzyme that adds a cap, or telomere, to the ends of chromosomes. As the caps wear away a little bit each time a cell divides, they are believed to contribute to aging in cells, whether in the body or growing in culture in the laboratory.

The increase in telomerase we see in the progenitor cells could be an added benefit of using this partial de-differentiation technique for the production of new blood vessels for patients with cardiac disease, especially for older patients, Rehman said. Their cells may already have shortened telomeres due to their advanced age. The process of converting and expanding these cells in the lab could make them age even further and impair their long-term function. But if the cells have elevated levels of telomerase, the cells are at lower risk of premature aging.

While telomerase has benefits, the enzyme is also found in extremely high levels in cancer cells, where it keeps cell division in overdrive.

We were concerned about the risk of tumor formation, Rehman said, but the researchers didnt observe any in these experiments. But to truly determine the efficacy and safety of these cells for humans, one needs to study them over even longer time periods in larger animals.

Partial De-differentiation Converts Skin Cells into Blood Vessel Cells ... - Technology Networks

Newswise Hematologist-oncologist Ahmad Samer Al-Homsi MD, MBA, will lead a new bone marrow transplantation program at NYU Langones Perlmutter Cancer Center for treating blood-borne cancers, including leukemia, lymphoma and multiple myeloma, and potentially utilize transplantation as an adjunct to immunotherapy for solid tumors. He also will investigate ways to reduce graft-versus-host disease (GvHD), in which immune cells in donated blood and marrow attack the tissues of a recipient.

In addition, Al-Homsi will facilitate NYU Langones collaboration with Johns Hopkins School of Medicine to institute haploidentical transplantation at PCC, in which less perfectly matched individuals can serve as donors. The advent of haplo-transplantation at Perlmutter Cancer Center will vastly expand the potential donor pool for patients who require a transplant.

Al-Homsi, who officially joins NYU Langone on June 1, 2017, most recently co-founded the blood and bone marrow transplantation program at Spectrum Health, a major multi-site health system in West Michigan. Prior to joining Spectrum, he was chief of the Division of Hematologic Malignancies & Blood and Marrow Transplantation and director of the stem cell laboratory at Roger Williams Medical Center in Providence, RI, an academic affiliate of Boston University School of Medicine. Al-Homsi also directed the blood and marrow transplantation program and held several clinical and academic posts at the University of Massachusetts and its affiliated medical center.

Al-Homsis research is focused on preventing GvHD, a potentially life-threatening complication of bone marrow transplantation. He has led clinical trials examining innovative combinations of medications to prevent GvHD , including cyclophosphamide and proteasome inhibitors. Such combinations can omit the need for extended and burdensome prophylactic traditional agents and are applicable to patients with limited kidney function who are often denied blood and marrow transplantation.

At Perlmutter Cancer Center, Al-Homsi will work closely with a strong hematology-oncology team that has made important advances in the study and treatment of blood-borne cancers. Patients requiring bone marrow transplantation undergo their treatment at the medical centers Rita J. and Stanley H. Bone Stem Cell/Bone Marrow Transplant Center.

His appointment also complements important programmatic and research efforts underway at NYU Langones Transplant Institute.

Our understanding of hematologic malignancies has advanced greatly over the past decade, to the point that many cases are curable, says Benjamin G. Neel, MD, PhD, director of Perlmutter Cancer Center. Bone marrow transplantation plays a critical role in these advances -- but it doesnt come without risk. Dr. Al-Homsis research holds tremendous promise to curtail negative interactions between host and transplanted cells and make this form of treatment safer and more effective.

About Dr. Al-Homsi

Al-Homsi earned his medical degree from the University of Damascus in his native Syria. He received training in Hematology at the University of Tours in Paris and in Clinical Oncology from the University of Paris VI in France. He then completed his training in the United States, serving an internship and residency in Internal Medicine at Christ Hospital and Medical Center in Oak Lawn, Illinois, and a fellowship in Hematology and Medical Oncology at the University of Massachusetts Medical Center.

His published studies have appeared in Transplantation, Leukemia, Transplant Immunology, Journal of Infectious Diseases, International Journal of Molecular Medicine, Bone Marrow Transplantation, and Biology of Blood and Marrow Transplantation. He also has authored many book chapters and review articles, and has served on editorial boards of several peer-reviewed journals in his medical specialty.

Al-Homsi also is a lead inspector for the Federation for the Accreditation of Cellular Therapy (FACT) and a member of its Clinical Standard Sub-Committee and Outcomes Improvement Committee.

I am delighted to join NYU Langone and its Perlmutter Cancer Center to build a nationally recognized bone marrow transplantation program, Al-Homsi says. We are defeating leukemia, lymphoma and myeloma at increasing rates. At the same time, we must continue to discover ways to ameliorate problems that sometimes come with treatment. I am confident we can make important strides.

Clinician-Researcher to Lead New Bone Marrow Transplantation Initiative - Newswise (press release)

M

ice that walk straight and fluidly dont usually make scientists exult, but these did: The lab rodents all had a mouse version of Parkinsons disease and only weeks before had barely been able to lurch and shuffle around their cages.

Using a trick from stem-cell science, researchers managed to restore the kind of brain cells whose death causes Parkinsons. And the mice walked almost normally.The same technique turned human brain cells, growing in a lab dish, into the dopamine-producing neurons that are AWOL in Parkinsons, scientists at Swedens Karolinska Institute reportedon Monday in Nature Biotechnology.

Success in lab mice and human cells is many difficult steps away from success in patients. The study nevertheless injected new life into a promising approach to Parkinsons that has suffered setback after setback replacing the dopamine neurons that are lost in the disease, crippling movement and eventually impairing mental function.

This is not going to happen in five years or possibly even 10, but Im excited about the potential of this kind of cell replacement therapy, said James Beck, chief scientific officer of the Parkinsons Foundation, which was not involved in the study. It could really give life back to someone with Parkinsons disease.

There is no cure for Parkinsons, a neurodegenerative disease that affects an estimated 10 million people worldwide, most prominently actor Michael J. Fox. Drugs that enable the brain to make dopamine help only somewhat, often causing movement abnormalities called dyskinesia as well as bizarre side effects such as a compulsion to gamble; they do nothing to stop the neurodegeneration.

As Parkinsons patients wait, Fox Foundation and scientist feud over drug trial

Rather than replacing the missing dopamine, scientists led by Karolinskas Ernest Arenas tried to replace dopamine neurons but not in the way that researchers have been trying since the late 1980s. In that approach, scientists obtained tissue containing dopamine neurons from first-trimester aborted fetuses and implanted it intopatients brains.Although a 2001clinical trialfound that the transplants partly alleviated the rigidity and tremors of Parkinsons, the procedure caused serious dyskinesia in about 20 percent of patients, Beck said. More problematic is that fetal issue raises ethical concerns and is in short supply.

It was clear that usable fragments of brain tissue were extremely difficult to recover, said Dr. Curt Freed, of the University of Colorado, who pioneered that work.

Instead, several labs have therefore used stem cells to produce dopamine neurons in dishes. Transplanted into the brains of lab rats with Parkinsons, the neurons reduced rigidity, tremor, and other symptoms. Human studies are expected to begin in the US and Japan this year or next, Beck said.

In the Karolinska approach, there is no need to search for donor cells and no cell transplantation or [need for] immunosuppression to prevent rejection, Arenas told STAT. Instead, he and his team exploited one of the most startling recent discoveries in cell biology: that certain molecules can cause one kind of specialized cell, such as a skin cell, to pull a Benjamin Button, aging in reverse until they become like the embryonic cells called stem cells. Those can be induced to morph into any kind of cell heart, skin, muscle, and more in the body.

Muhammad Ali and Parkinsons disease: Was boxing to blame?

Arenas and his team filled harmless lentiviruses with a cocktail of four such molecules. Injected into the brains of mice with Parkinsons-like damage, the viruses infected plentifulbrain cells called astrocytes. (The brains support cells, astrocytes perform jobs like controlling blood flow.)The viruses also infected other kinds of cells, but their payload was designed to work only in astrocytes, and apparently caused no harm to the other cells.

The molecules, called transcription factors, reprogrammed some of the astrocytes to become dopamine neurons, which were first detected three weeks later in the mouse brains. The dopamine neurons were abundant 15 weeks later, an indication that after changing into dopamine neurons the astrocytes stayed changed.

Five weeks after receiving the injections, the mice, which used to have Parkinsons-like gait abnormalities, walked as well as healthy mice. That suggests that direct reprogramming [of brain cells] has the potential to become a novel therapeutic approach for Parkinsons, Arenas told STAT.

That could have value for preserving the brain circuitry destroyed by Parkinsons, said Colorados Freed.

A lot of hurdles need to be overcome before this becomes a Parkinsons treatment. The Trojan horse system for delivering the reprogramming molecules inside viruseswould need to turn more astrocytes into dopamine neurons and leave other kinds of cells alone: Although viruses getting into mouse brain cells apparently caused no harm, that might not be so in people. We will need to use virus with selective [attraction] for astrocytes, Arenas said.

The morphed cells would presumably be ravaged by whatever produced Parkinsons in the first place. But in other cell transplants, Arenas said, the disease catches up with transplanted cells in 15 to 20 years, buying patients a good period of time. He thinks it might be possible to give patients a single injection but hold off some of the reprogramming with a drug, turning it on when the brain again runs short of dopamine neurons.

The basic technology to develop such strategies currently exists, he said.

The Karolinska lab is working to make the techniquesafer and more effective, including by using viruses that would deliver reprogramming molecules only to astrocytes. We are open to collaborations aimed at human studies, Arenas said.

Would patients be willing to undergo brain injections? People with Parkinsons disease, Beck said, are willing to go through a lot for any hope of improvement.

Mighty morphed brain cells cure Parkinson's in mice, but human trials still far off - STAT

NEWMARKET Karen Olivier is excitedly looking forward to what she calls her stem cell birthday.

Olivier, 40, is traveling April 23 to Monterrey, Mexico, to undergo a procedure that will reset her immune system and stop the inflammation in her body, caused by her relapsing-remitting multiple sclerosis.

Diagnosed with MS at the age of 24, Olivier learned about a treatment called hematopoietic stem cell therapy, or HSCT, from a Facebook page. It gave her hope that if she had this treatment, it would stop the progression of the disease.

She began blogging about her journey leading up to her trip to Mexico.

I want others to know this is an option, she said.

According to the National Multiple Sclerosis Society, HSCT attempts to reboot the immune system, which is responsible for damaging the brain and spinal cord in MS. In HSCT, hematopoietic (blood cell-producing) stem cells are derived from the persons own bone marrow or blood, are collected and stored, and the rest of the individuals immune cells are depleted by chemotherapy.

The stored hematopoietic stem cells are then reintroduced to the body. The new stem cells migrate to the bone marrow and, over time, produce new white blood cells. Eventually they repopulate the body with immune cells, building a new immune system that doesnt know what MS is.

In early clinical trials, 78 percent of participants experienced no new disease activity after the procedure and did not need disease-modifying therapies to control their disease.

Olivier had been taking disease modifying drugs, or DMDs, for 15 years, starting with Avonex, a once weekly intramuscular injection. She then took Rebif, a subcutaneous injection three times a week. After she took a daily injection of Copaxone. In 2009, she started on Tysabri, receiving an infusion every 28 days.

I did well on the Tysabri, but in the past couple of years, my symptoms progressed and my most recent MRI showed new disease activity on my thoracic spine, Olivier said. At the rate my MS was progressing, I would probably be in a wheelchair in two years.

Since 1993, the Federal Drug Administration has approved DMDs to treat relapsing-remitting MS. All are designed to suppress the immune system to one degree or another. These drugs cost about $5,000 per month and they must be taken indefinitely, since relapses will occur if the drugs are stopped.

Oliviers insurance covered the cost of the drugs, but her copays and coinsurance amounts were still very high, she said. One month of a DMD infusion can cost between $7,000 and $9,000.

Olivier researched a clinical trial of HSCT in Chicago, a program begun in 1996 by Dr. Richard Burt, now chief of the division of medicine-immunology and autoimmune diseases at Northwestern Universitys Feinberg School of Medicine.

Trial criteria included relapsing-remitting MS, and failure on at least two DMDs and two flare-ups in the past 12 months, requiring treatment from steroids, she said.

In the United States, HSCT can cost between $150,000 and $200,000.

Insurance may have covered it out-of-network, but my plan has a substantial out-of-pocket maximum, Olivier said. It would have require multiple trips to Chicago for several years, and I could have ended up in the control group.

Olivier began to explore receiving HSCT in other countries and decided to apply for the treatment at Clinica Ruiz in Mexico last October when she was recovering from a flare-up. Clinica Ruiz is based in Pueblo, Mexico, but has expanded to a second clinic in Monterrey.

She and her husband, Jason, agreed spend the $54,500 out-of-pocket cost for the outpatient treatment that also includes transportation to and from a two-bedroom apartment where she will stay for 28 days. Her mother is traveling with her, as the treatment protocol requires the patient to have a caregiver present.

I was accepted based on my MS history and my expanded disability status scale (EDSS) score that basically measures how mobile you are, Olivier said.

Olivier will undergo two days of chemotherapy to wipe out her immune system. She will then have seven days of injections to promote stem cell growth, after which stem cells will be harvested from her blood.

Ill then have two more days of chemotherapy, she said. Im excited. No chemo, no cure.

May 7 will be what Olivier calls her stem cell birthday when she receives her stem cells back to reboot her immune system. She will then be in isolation in the apartment for about a week. Her mother will have to wear special precaution gear during that time.

Some people see improvements in the first three months, with full recovery in two years, Olivier said. Some might say Im not sick enough for this treatment, but the earlier someone gets it, the better, before the MS causes major damage.

She added that some people believe this is a risky procedure and it has not been FDA-approved yet in the United States.

But many people have died on Tysabri and the drug approved by the FDA last week, Ocrevus, has an increased risk of cancer after two to three years. I am hoping the HSCT will stop the progression of my MS, and hope that I never have to go on another DMD in my life.

A stem cell treatment for heart failure patients is safe and shows early signs of effectiveness, according to a study published Wednesday.

The study was conducted by Japanese researchers in 27 patients, who received transplants of stem cells taken from their own thigh muscles. There were no major complications, and most patients showed considerable improvement in their symptoms.

The study was published in the open-access Journal of the American Heart Association. Dr Yoshiki Sawa of Osaka University Graduate School of Medicine was the senior author. It can be found at j.mp/stemheart.

However, two San Diego cardiologists who do stem cell research on heart disease cautioned that similar clinical trials have shown promise over the years, only to fail at the end for various reasons. There is no approved stem cell therapy for heart failure.

So while the trial itself appears to be well-conducted, the researchers are very far from actually proving their treatment is effective, said Dr. Richard Schatz of Scripps Health and Dr. Eric Adler of UC San Diego School of Medicine.

For one thing, the trial was small, they said, and larger trials are where the most rigorous scientific evaluations are made.

These early trials have looked beneficial in the past, Adler said. When we do the larger trials, the results are more equivocal.

Adler said the signs of efficacy in this trial are modest. For example, the change in ejection fraction, a measurement of efficiency in pumping blood, rose from 27 percent to 30 percent in 15 of the 27 patients. Their heart failure was associated with a lack of blood flow, or ischemia. The remaining non-ischemic patients actually had a slight decline.

The entire field of stem cell and regenerative therapy for heart disease has been a disappointment to date, Schatz said.

Weve been at it for 20 years now, and we dont have a product or a positive (late-stage) trial, so that tells you pretty much everything you need to know, he said. Its not for lack of trying or billions of dollars invested. Its just very, very difficult.

The cardiac field has had more success with other technologies, such as cardiac stents. Schatz is the co-inventor of the first stent.

In the study, the researchers acknowledge that previous attempts had only been modestly effective. They devised a method of producing sheets of muscle stem cells and attaching them to the inner layer of the sac that encloses the heart, a layer that rests directly on the heart surface.

The stem cell sheets stimulate healing by producing chemicals that stimulate cardiac regeneration, the study said. The cells themselves dont survive in the long term, but by the time they die they have served their purpose.

Loss of function

Heart failure is a progressive disease in which the heart gradually loses its ability to pump blood. This can be triggered by a heart attack or any other cause that damages the heart muscle.

When damaged heart muscle is replaced with scar tissue, as often happens, the heart loses pumping capacity. It becomes overstressed, and its output of blood declines. This limits the patients ability to engage in intensive physical activity. In advanced cases, patients may become bedridden.

Existing treatments include drugs and LVAD units, which take over some of the hearts function to relieve stress. Some drugs may help the heart work more efficiently, but none have been shown to improve heart failure by actually regenerating lost heart muscle.

Stem cell therapy is tested in patients who havent responded well to other treatments. Trials have been and are being conducted in San Diego area hospitals.

Scripps Health has been testing a cardiac stem cell therapy from Los Angeles-based Capricor. The cells, taken from donor hearts, are injected into the coronary artery, where they are expected to settle in the heart and encourage regrowth.

UC San Diego is testing a heart failure therapy from Teva Pharmaceutical Industries. It consists of bone marrow derived mesenchymal precursor cells. These can give rise to several different cell types, including muscle cells.

And many other trials are going on throughout the country and internationally.

Adler and Schatz said theres reason for optimism in the long run, as technologies improve.

Just because the other trials have been negative doesnt mean this technique wont be beneficial, Adler said. Its just too early to tell.

That said, Schatz emphasized that the nature of the three-phase clinical trial process means that the show-stoppers for a treatment typically appear late.

Tighter standards needed

Clean trials trials where we all agree that this is the patient population we want to look at, are needed, he said.

For example, heart failure comes in two types, he said. Ischemic heart failure is caused by heart attacks and blocked arteries, which impede blood flow. Non-ischemic heart failure can be caused by damage from diseases, such as a virus.

Non-ischemics can be younger people, in their 20s and 30s, while the ischemic patients are older. Mixing those patient groups in a single trial is a mistake, he said.

Theyre different animals, Schatz said.

Another pitfall is failing to screen carefully enough to enroll only patients likely to benefit, Schatz said.

You can have a patient who has chest pain, and coronary disease just incidentally, he said.

His shoulder or chest pain is from a virus. So he goes into the trial and gets a placebo injection in his arm of cortisone, and his arm pain goes away. And because hes in that placebo group, hes counted as a success the pain went away. It has nothing to do with his heart. Thats an extreme example, but we actually saw that happen.

In a failed gene therapy trial for heart disease, some patients apparently had received the injection in the wrong location, missing the heart muscle, Schatz said.

You assume they got the gene, but they didnt, Schatz said. The study was negative, and thats why I think it was negative.

Such errors dont show up in Phase 1 trials, Adler and Schatz said, because theyre focused on evaluating safety. And these early trials dont have many patients, there arent enough to comfortably determine the therapy is really effective.

By the last stage of the trial, these sources of error have often been identified and trial standards have tightened up. And thats when the faulty assumptions made early appear as the trial ends in failure.

Despite those forbidding hurdles, Adler said research should continue.

This disease is killing a lot of people. Theres not going to be enough hearts to go around for transplant. Theres six million Americans with heart failure, and theres 2,000 heart transplants a year. So coming up with novel regenerative cell-based therapy is something were still excited about.

BROOKLINE Fighting for her life, a retired Brookline teacher who has been struggling with cancer for more than four years is hoping to find a donor for a stem cell transplant.

This week, Kathi Bond of Temple has undergone 96 hours of around-the-clock chemotherapy, but next week provides a new and unique opportunity for the 66-year-old woman battling a bone marrow cancer known as multiple myeloma.

A marrow donor registry drive will take place on Tuesday in an effort to find a match for Bond, who has undergone numerous, unsuccessful therapies throughout the past several years.

She is not the type that wants to be lying in a bed staring at a blank wall she would rather be climbing mountains, said Bonds husband, David Bond. She is a very vibrant woman, but on paper she is very ill.

Kathi Bond, who retired in 2013 from her environmental science teaching position in the Brookline School District because of the cancer, has already undergone an autologous stem cell transplant where her own cells were used for the procedure.

While this effort placed her in remission for more than a year, her body eventually began to reject the treatment and she fell ill again in the fall of 2016, and is now at stage 3 multiple myeloma.

I think emotionally, for any cancer patient, it is a roller coaster, said David Bond. You have good days and bad days glimmers of light and then news that things arent working.

Multiple myeloma is a plasma cell disorder that attacks cells in a persons bone marrow. Since traditional treatments are not working for Kathi Bond, doctors are now looking for radical ways to preserve her life, and a donor transplant is the next alternative.

Unfortunately, at this point, they have not found a match for Kathi, said her husband. But we have always felt that optimism is stronger than adversity. There will be a match out there somewhere.

A marrow donor registry drive will take place from 3:30 p.m. to 7 p.m. Tuesday at the Richard Maghakian Memorial School, 22 Milford St. in Brookline. Participants must be ages 18 to 44, and will have their cheek swabbed to determine compatibility.

Kathi Bond, who is currently hospitalized, is attempting to reduce the number of myeloma cancer cells in an effort to make the future transplant more successful. She is working with an oncologist in Nashua, and the Dana-Farber Cancer Institute to determine the best course of action for an incurable illness.

She is fairly strong right now, but a transplant is desperately needed, said David Bond.

Cancer is no longer a private struggle, he said, adding it affects so many families. In 1984, Kathi Bond lost her older sister to lymphoma.

At the time, he said there were no donor drives, walks for cancer or fundraisers to research cancer treatments.

Today, we save lives because we share our story, and compassionate people step forward and join the fight, he said.

The Bonds are hopeful to find a match from next weeks marrow donor registry drive, but said even if they dont, the data may be useful in helping to find a match for someone else in desperate need.

Kathleen Milewski, a second-grade teacher at RMMS in Brookline, along with the Bonds two daughters, have been instrumental in helping to organize Tuesdays drive, according to David Bond.

Joining the registry is as simple as a cheek swab, and the donation process, should you be a match, is similar to giving blood in over 70 percent of the cases, said Milewski. Kathi needs a match in order to continue to live with multiple myeloma.

David Bond said a donor transplant is his wifes greatest hope for a life of near-normalcy. A donors stem cells will result in a total reboot of the patients marrow, and as new donor stem cells develop and mature, they will over-populate the bad cells.

April 5, 2017 Stem cells (red) on polycaprolactone-based microcarriers. Credit: Elsevier

Bone tissue engineering is theoretically now possible at a large scale. A*STAR researchers have developed small biodegradable and biocompatible supports that aid stem cell differentiation and multiplication as well as bone formation in living animal models.

Mesenchymal stem cells self-renew and differentiate into fat, muscle, bone, and cartilage cells, which makes them attractive for organ repair and regeneration. These stem cells can be isolated from different sources, such as the human placenta and fatty tissue. Human early mesenchymal stem cells (heMSCs), which are derived from fetal bone marrow, were thought to be best suited for bone healing, but were not readily accessible for therapeutic use.

Existing approaches to expand stem cells for industrial applications tend to use two-dimensional materials as culture media, but their production yields are too low for clinical demand. Furthermore, stem cells typically need to be harvested with enzymes and attached to a scaffold before they can be implanted.

To bring commercially viable cell therapies to market, Asha Shekaran and Steve Oh, from the A*STAR Bioprocessing Technology Institute, have created directly implantable microscopic spheres in collaboration with the A*STAR Institute of Materials Research and Engineering. These spheres, which acted as heMSC microcarriers, consist of a biodegradable and biocompatible polymer called polycaprolactone.

According to Shekaran, their initial aim was to expand stem cells on microcarriers in bioreactors to scale up production. However, this strategy threw up difficulties, especially when attempting to effectively dissociate the cells from the microcarriers and transfer them to biodegradable scaffolds for implantation.

"A biodegradable microcarrier would have a dual purpose," Shekaran says, noting that it could potentially provide a substrate for cell attachment during scalable expansion in bioreactors, and a porous scaffold for cell delivery during implantation.

The researchers generated their microcarriers by synthesizing polycaprolactone spheres and coating them with two proteins polylysine and fibronectin. These proteins are found in the extracellular matrix that assists cell adhesion, growth, proliferation, and differentiation in the body.

Microcarriers that most induced cell attachment also promoted cell differentiation into bone-like matrix more strongly than conventional two-dimensional supports. In addition, implanted stem cells grown on these microcarriers produced an equivalent amount of bone to their conventionally-derived analogs.

"This is encouraging because microcarrier-based expansion and delivery are more scalable than two-dimensional culture methods," says Shekaran.

The team now plans to further investigate the therapeutic potential of these microcarrierstem cell assemblies in actual bone healing models.

Girl still in need of bone marrow match - Temple Daily Telegram

Around 6,000 hematopoietic stem cell transplantations are carried out annually in Iran using the patients own cells, and a far higher number are performed using cells from donors who are often close relatives of the patient, according to the Hematology-Oncology Research Center and Stem Cell Transplantation (HORCSCT) affiliated to the Tehran University of Medical Sciences. Ardeshir Qavamzadeh, head of the center, said the number of stem cell transplants is on par with developed countries. The success rate in the treatment of diseases requiring transplant is 67% at HORCSCT, ISNA quoted him as saying. Referring to the fast and progressive development of stem cell discipline in Iran, he said since 1983, when the adult leukemia specialty was initiated in the country, nearly 300 specialists have been trained in the field and there is at least one specialist in each province now. Today, one cannot find a treatment method of stem cell transplant in the worlds advanced research centers that is not available or practiced in Iran. We have reached a level where we can compete with the developed nations. HSCT Hubs There are 10 hubs for hematopoietic stem cell transplant (HSCT) in the country. Each includes medical universities from the provinces with one as the focal point. Medical universities of Zanjan, Qazvin, Alborz and Qom comprise one of the hubs with Zanjan as the center, said Mehdi Eskandari, education deputy at Zanjan University of Medical Sciences. HSCT is the transplantation of multi-potent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. It may be autologous (when the patients own stem cells are used) or allogeneic (stem cells from a donor). It is a medical procedure in the field of hematology, most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukemia. Since HSCT is a relatively risky procedure with many possible complications, it is reserved for patients with life-threatening diseases. However, as the survival rate following the procedure has increased, its use has expanded beyond cancer, including in autoimmune diseases, blood diseases like thalassaemia major, metabolic disorders, alcoholic liver, and even rheumatism.

Stem Cell Transplant Making Rapid Progress - Financial Tribune

LORENA, Texas (KWTX) Lorena residents and others from around Central Texas turned out Monday to register as bone marrow donors in support of a first grade teacher with a rare medical condition, the only cure for which is a bone marrow transplant.

Melinda Colyer, who teaches at Lorena Primary School, was diagnosed with myelodysplastic syndrome with myelofibrosis about two weeks ago.

"It's actually a disease that causes the destruction of your stem cells in your bone marrow. They do consider it a form of cancer. The only cure that will be provided is through a bone marrow transplant, Colyer said.

She said receiving the news was tough, but she says shes a fighter.

I decided to pick myself up and was able to go forward and that's what I'm doing at this point, said Colyer.

Lorena Primary School Principal Liza Cunningham said Colyer shines with positivity despite the diagnosis.

"Ms. Colyer is one of the most upbeat people you will ever meet in your entire life. She always has a positive attitude, she has a love for kids. It's very apparent in everything she does, said Cunningham.

The drive Monday was held at Midway High Schools Distance Learning Center.

The process takes less than five minutes, and involves a mouth swab to collect DNA samples.

Prospective donors must be in good health and between the ages of 18 to 44.

Anyone interested in becoming a bone marrow donor can sign up with Scott & Whites Marrow Donor Program.

"She wants everybody to go out and be tested because even if we are not a match for her, we would be a match for somebody else. And that's really what she's been telling us about this whole event and that's very selfless of her, Cunningham said.
